A flange is a component that is used in pipework systems for connecting and attaching pipe, valves, pumps, and so on. As an external or internal ridge, or rim, flanges are usually designed to interface sections of pipe and enable easy assembly and disassembly.

Typically, a flange is a forged or thrown ring of stainless steel that is welded or screwed to another component in the system. To create a flanged joint in a pipe system, two connecting pieces with flanges at the end are bolted together with a seal provided by a gasket in between them.

The dimensions of flanges are determined by the size of the pipe as well as the pressure class required for the application. The pressure class ratings that flanges are designed to are: 150 lb, 300 lb, 400 lb, 600 lb, 900 lb, 1,500 lb, and 2,500 lb. There are many different flange standards worldwide, with organisations such as ASME, MSS, and API publishing standards.

There are several different types of flanges, including:

* Groove/tongue: This combination of a raised ring (tongue) and depression (groove) align together precisely.
* Slip-on: This flange slips over the pipe and is welded at the top and base side.
* Blind: This is a plate for covering or closing the end of a pipe, mainly used as part of high pressure weight applications.
* High hub blind: This is a simple round plate without a centre hold.
* Expander: The non-flanged end is larger than the flanged end. This is used to change the size of a pipe run.
* Weld neck: This helps transfer stress from flange to pipe, and is therefore suitable for high pressure applications.
* Threaded: This flange is fixed to a pipe using only threads and not welding, and so are more common for low pressure applications.
* Socket weld: Pipes are inserted into the sockets of flanges and welded for smooth flow. Tends to be used with smaller pipes.
* Weldo/Nipo: A combination of weld neck flange and a nipolet (a one-piece fitting for valve take-offs, drains and vents).
* Reducing: Used in applications with different pipe diameters.
* Square: Square-shaped and has the advantage of being durable and with a dependable isolation point.
* Spectacle: Comprises two discs attached with the help of a small metal (usually stainless steel, alloy steel, etc.) section.
* Orifice: Typically used with orifice metering systems for gauging liquid and gas flow rates.
* Ring type joint: A metal ring with hexagonal groove compressed to a flange to form a seal.
* Plate: Similar to a gasket, and are typically used in applications made from casting.
* Lapped joint: Used on applications with lap joint stub ends or lapped pipes, typically where cleaning or inspection is regularly required.
